Abstract
A time synchronization network able to efficiently maintain time synchronization according to standard time is described. A communication device includes a time information output unit and a time synchronization unit. The time information output unit is configured to output time information with an internal clock that is stable. The time synchronization unit is configured to correct the time information of the time information output unit based on information on a time difference between the communication device and another communication device adjacent to the communication device.
